Dan's latest podcast "Factors affecting depth" Listen at: http://thetreasurecorner.com prompted me to address a question I've had for some time about discrimination and depth.
The normal thought process, mostly due to posts, is that lower discrimination gives you more depth. What concerns me about this belief is that my experience, and experiments, have shown nothing to support this claim. Now it could be that the detectors I have tested this theory on just happen to be of the type where it doesn't apply?
I'm asking this more as a question than a statement.
Try it for yourself. Turn on your detector and pick a basic notched, for those with a notch system, or preset program that uses discrimination. For me I used the stock Coin & Jewelry mode on my DFX and Eagle Spectrum. Run a coin over the coil and get an idea of how far away you can hold the coin and still get a signal. Now mark that spot and remember it. Next turn your discrimination all the way down and do the same. Did you gain any depth? How much? What detector are you using?
Now don't get me wrong I'm all for less discrimination, but at least in my case, it seems to be less discrimination doesn't equal more depth, but better response from more targets. In any case less discrimination is without a doubt a good thing, but are we using the wrong description(increased depth) to describe its benefits? Should we be saying less discrimination gives better response to targets?
Again, this is a question rather than a statement. I can only speak for my experience and testing on a few detectors.
